Spammer in chat that can not be reported or muted.

Hello,

There is an annoying spammer of cheat software in the chat room that has his name NOT showing up so you can not even mute that account, not even mentioning being able to report it using steam report system. There is just no way to look up the account that's doing it.

Please can some admin elevate it and maybe find and ban that account... hopefully something can be done also about not being able to click on the messenger name and report it.
